go - Golang Operator Overloading

I understand that golang does not provide operator overloading, as it believe that it is increasing the complexity.

So I want to implement that for structures directly.

package main

import "fmt"

type A struct {
    value1 int
    value2 int
}

func (a A) AddValue(v A) A {
    a.value1 += v.value1
    a.value2 += v.value2
    return a
}


func main() {
    x, z := A{1, 2}, A{1, 2}
    y := A{3, 4}

    x = x.AddValue(y)

    z.value1 += y.value1
    z.value2 += y.value2

    fmt.Println(x)
    fmt.Println(z)
}

https://play.golang.org/p/1U8omyF8-V

From the above code, the AddValue works as I want to. However, my only concern is that it is a pass by value and hence I have to return the newly added value everytime.

Is there any other better method, in order to avoid returning the summed up variable.
